Black parts - Super Record and NR-SL pedals do not fit the pattern. Also, the black arms on the SR front derailleur don't fit the pattern.
These are the only exceptions so far.
But. . . aren't SL pedal cages heat-treated or something? The other black details might be mere cosmetics to delineate SR from the rest.
